Brief Introduction

  U9825/U9845/U9805X series impulse winding tester adopts high stability & high-voltage impact power and thyristor module controlled high-voltage switching devices, which bring a substantial increase in the stability and reliability of the product. With advanced 32 bit CPU and high speed FPGA, 100Msps sampling rate and memory depth of 6500 bytes make the test more precise; the use of high speed testing technique make the maximum test speed up to 12 meas/sec. 

Comparison test function

Without collecting standard waveforms, the consistency of two tested coils can be compared rapidly.

    

 

 

 Corona display function

Up to 100Msps sampling rate ensure precise extraction of corona information. The equipped corona display function make corona information and product performance clear and visualized.
